Yes, thanks for mentioning it. There will be a pointer to that (free Kindle, cheap paperback specifically about this Seeed display) on the free CD. But you made me realize having my Kindle on the table tomorrow would be a good idea. :-)

To Alex' point, the SPI bus I/O with Arduino is not even buffered, let alone DMA-driven with a high clock rate, so don't expect to watch YouTube videos. I had hoped to see what a pair of 240Mhz ARM cores could accomplish but those boards have not cleared customs in NYC yet.

And I've decided to sell 10ml bottles of AIM 280 no clean liquid flux designed for surface mount soldering (with the little tethered cap on a thin applicator tube) for $5, or less than half the cost of a high end flux pen.

But, in case anybody is getting the wrong idea, I'm not starting a retail sales empire. I had to buy a gallon of AIM280 in order to get a drop. These are both one-offs, as far as I'm concerned.

Pete, have you seen this resource? I just downloaded a copy of it (free download) and it looks like a great overview of using the LCD for a couple of interesting GUI displays.

    My daughter's grad school plans have brought my un-retirement
    process into sharper focus, and the value-add proposition I'd
    promised myself for some ex-Radioshack stock hasn't panned out
    yet, so the time for this is now.

    Full details for $20 touch screen displays are on the Triembed web
    site here

    I'll be selling them at RARSFest <http://www.rars.org/rarsfest/>
    tomorrow (yellow table, blue custom triangle made out of plastic
    cups). If you're at the TAR or TriEmbed meetings these next two
    Mondays feel free to inquire privately about stock unsold at the
    'Fest that I will sell with the same terms (cash, check, or
    PayPal). I'll wear an AD4L amateur radio badge to avoid any
    solicitation on campus.

    Regards,
    Pete
